Light Therapy

Depression and stress have a tendency to intermingle, making it difficult to put your finger on the exact reason why you feel depressed or stressed. You may even feel that it’s
not one thing that’s getting you down. It’s everything, and you just can’t seem to kick a consistent feeling of gloom? You can probably categorize those feelings as depression.

For some people that feeling of gloom and depression is called SAD, Seasonal Affective Disorder. SAD is a depression disorder associated with light deprivation during the winter
months. Seasonal Affective Disorder is caused by a melatonin imbalance initiated by a lack of exposure to sunlight. SAD sufferers are not the only ones feeling stress, depression and the negative health affects caused by a lack of appropriate sunlight. We are all feeling its impact. Our lifestyles limit our exposure to sunlight. You naturally get vitamin D from sunlight, and a lack of exposure to sunlight is the main cause of vitamin D deficiency.

Vitamin D deficiencies can cause severe health issues. Osteoporosis is linked to a lack of vitamin D. Rickets is another bone-wasting disease that is linked to a vitamin D deficiency, and chronic vitamin D deficiency is often misdiagnosed as Fibromyalgia, because the symptoms are so similar; muscle weakness, depression, and unexplained aches and pains.

You can get vitamin D through food and supplements, but sunlight exposure is the only reliable way to generate vitamin D in your body. Studies show that healthy levels of vitamin D inhibit prostate cancer, breast cancer, ovarian cancer, colon cancer, depression, and even schizophrenia.

People with dark skin tend to need 20 – 30 times as much exposure to sunlight as fair-skinned people to generate the same amount of vitamin D. In fact, doctors have now discovered that vitamin D deficiency is causing high rates of prostate cancer in Black males. People who are over weight have been found to need twice as much vitamin D, because obesity tends to impair how the body utilizes vitamin D. In general, studies show that your risk of developing serious
diseases like diabetes and cancer can be reduced by 50% - 80% with simple and sensible exposure to natural sunlight on an average of two to three times each week.

When your exposure to natural sunlight is limited, you can combat the depression related to SAD or the health issues associated with sunlight deficiencies with light therapy or photo therapy. Light therapy is exposure to light through special light therapy lamps or light boxes that are brighter than indoor light, but not as bright as direct sunlight. Light therapy has been found to be effective against depression, and it can reset your biological clock, or circadian rhythms, which controls when you sleep and when you wake up. Exposure to this special light has been found to be close enough to natural sunlight to allow the body to produce needed vitamin D.

Light therapy can offer effective mood altering and physical health benefits for generally anyone, and it has already been clinically proven to reduce stress.

Light therapy may be most effective when used first thing in the morning when
you wake up. You and your doctor can determine when light therapy works best
for you. You usually sit approximately 12" from the light anywhere from 10 to 30
minutes per session. It is neither recommended nor necessary to stare directly
into the light. A positive response to light therapy usually occurs within 2 to 4
days, but it may take up to three weeks before symptoms of SAD or depression
are relieved, and it can take months to correct a vitamin D deficiency.

We can all benefit from the use of light therapy. More often than not, most
people usually do not get the kind of exposure to the sun that could be
beneficial. You tend to be stuck inside buildings all day long. You may go to
work before sunrise, and get out of work as the sun is going down, or has
already set. If that sounds like your lifestyle, you may be a good candidate for
light therapy.

Light therapy is a viable alternative to consider when stress or depression has
taken over, and you need more than aromatherapy, candles, or relaxation to get
results.

That is really interesting dear Prattle!!
It also explains why the suicidal rates in countries with less sunlight is higher!
Although I believe it will raise in Greece soon too because of the economic crisis... whats the cure for that? Oh, I know! A MONEY TREE!!

I've heard that about suicidal rates too.. My sister in law suffers from SAD and needs to take antidepressants in the winter to balance out her moods.
